A CMSDigestedDataInputConnector is used in place of a CMSDigestedDataInputStream when reading nested CMS objects containing digested-data structures.

A CMSDigestedDataInputConnector is essentially a input stream filter that unwraps the CMS digested-data structure from the data read in. A CMSDigestedDataInputConnector expects the Content field of the CMS ContentInfo structure i.e. the underlying input stream must be positioned just after the explicit [0] tag wrapper.
